BMWs are high-end European automobiles, thus any power steering fluid won’t do. When you use high-quality fluid that matches the design of your BMW, you can truly sense the difference in driving when compared to others that have been tuned expressly for fancy automobiles like these. There are a few options available for your BMW power steering fluid, but if you want to keep your beautiful BMW in peak condition, you shouldn’t go too far from them. The best power steering fluids for a vehicle like this are listed below:
- Power steering fluid with pentosin. Pentosin power steering fluid is the brand’s top fluid, according to the manufacturer. It keeps your car’s steering system operating like a dream and was created with BMW requirements in mind. Pentosin CHF-11S is required for BMW vehicles made after 1990, while CHF7.1 is needed for earlier models.
- Automatic transmission fluid, Dexron III. If your BMW can accept ATF, this is next to Pentosin in terms of fluid quality. Dexron is a fantastic option for your car’s power steering fluid provided your BMW owner’s handbook says that you can use that with your model. If not, check to see what the manufacturer has to say about ATF.
- Power steering fluid made by Prestone with a stop leak. Although not specifically designed for BMW, this is useful for models that were produced before 2012 since it’s a great additive for vehicles that once used ZF hydraulic power steering racks, which BMWs had.
- J1B1001 Power Steering Fluid by Ravenol. Another good aftermarket alternative for your BMW is ravenol. It aids in the prevention of corrosion and fosters thermal stability and was specifically designed with luxury vehicles like BMW in mind.
- European Power Steering Fluid from Prestone. This synthetic fluid was created especially for BMW and other European vehicles. It’s a wonderful alternative for topping off your power steering fluid to keep your BMW running at peak performance with no noise or wear and tear, even though it’s a bit pricy for the very small quantity you receive. Having said that, alternative steering fluids offer greater value for the money.
We must make it clear that, if at all feasible, you must choose the Pentosin power steering fluid that corresponds to the model year shown as the first option in the above list. The Pentosin is what the manufacturer recommends universally, while the other possibilities may work well for your model if your owner’s manual specifies that other types may be used in it.

ATF or CHF for BMW power steering fluid?
What kind of power steering fluid does your car require, and what color is it? Of course, that depends on who you ask and what your car needs.
The majority of vehicles, including the BMW E39 5-Series, the majority of BMW E38 7-Series, and many more, rely on normal cherry-red ATF for power steering assistance. Today, I’d like to talk about the selection of 1990s BMWs that utilize the recognizable brilliant green paint Pentosin CHF-11S.
BMW employs CHF, or central hydraulic fluid, because the power steering pump also powers the vehicle’s hydraulic systems in addition to the steering gear. Some variants have a part known as a “tandem vane pump,” which enables the pump to power multiple automobile circuits simultaneously. Other designs merely have a regulator that divides the output of a single pump into various circuits. The power brake assist is hydraulically controlled in the BMW E31 8-series. The rear suspension features a hydraulic component on vehicles with self-leveling suspension, such as the E38 750iL or M5. This concept is also used by the Mercedes S600’s ABC (active body control) suspension, which uses hydraulic components at each corner of the vehicle to provide brake fluid to each caliper in a manner akin to that of a brake master cylinder. For all of the circuits that the pump drives, the same fluid reservoir is often utilized.
I’ve heard too many stories about technicians or prior owners filling a reservoir designed for CHF with regular ATF. This issue has affected four of the automobiles I’ve personally owned, and I’ve heard of many more. Why does this matter? Mixing oils and ATF is generally not a good idea because it has been shown to weaken the diaphragm of the nitrogen-filled accumulators used in the self-leveling suspension of BMW vehicles and to slowly degrade hydraulic seals. This causes those cars’ rear suspension to progressively become considerably harsher over time, and in the case of the hydraulic E31/E32 brake systems, it causes the loss of instantaneous braking force. Avoid making this error in the first place because replacing hydraulic accumulators can be very expensive.
It’s a good idea to examine the fluid’s color if you recently purchased a secondhand BMW. This image displays the awful dark red fluid I forced from an E31 850Ci when it was supposed to have brilliant green CHF-11S. (CHF 7.1 on earlier models).
Pumping the fluid out through the reservoir is typically the simplest option if you discover that your car has the incorrect fluid or the fluid is simply old and filthy looking. Refill with fresh fluid, start the engine to circulate it, and then do it again until the fluid is mostly brand-new. Although a little wasteful, this technique is required because these devices lack a straightforward drain plug. Unfortunately, this is the only way to reliably perform the service because a significant amount of fluid is trapped in the hydraulic components and will not easily drain from one central point.
